One thing Jen had always been curious about were cocks. Yes, she had seen the Sex-ed pictures and diagrams, and had even walked in on her father once while he was getting out of the shower. However, despite here reputation as a liar, she was not a slut. She had never even touched a cock with her own hands, let alone actually fucked a boy. This made her next change. Sitting down on her bed, she voiced a blatent lie.
"I have green hair."
The familiar tingling feeling washed over here mare cunt, before extending upwards into her womb. She could feel her canal closing up, sealing into one solid piece of flesh. As it did so, her clit started to extend, getting longer and thicker, skin growing over it. It stopped at a respectable five and a half inches long, and about an inch and a quarter wide. Looking under it, she could see her pussy lips sealing together to form an empty sack of flesh. The emptiness was soon rectified as two average size testicles dropped one at a time into her sack.
The tingling finally retreated and Jen reached down to grasp the gently throbbing, erect cock. As her hand wrapped around it, she shuddered as intense sensations rocketed up her spine to her brain. This felt great! No wonder guys always seemed to think with their dick, if this was how it felt to them!
Slowly starting to pump, the foreskin bunching and stretching, Jen pleasured herself for the first time as a male. Her other hand reached down and gently fondled and rolled her new balls in her palm. Soon, the gentle stroking had turned into frantic jerking, a slow, simmering heat building up in her balls and behind her cock. Slowly, that heat increased bit by bit, as did her pleasure, her cock getting harder as she got closer to orgasm. Finally, the heat boiled over and her balls pulled up tight against her body, as her cock got harder still, twitching and throbbing as streams of pearly white cum shot from the tip. Jen reflexively clenched the hand on her cock, providing even more pleasure.
Finally, she came down from her high and flopped back on her bed, tits spilling over her chest and cock going limp to hang over her balls between her spread legs.
